AI-Powered supplier vetting
SummaryWuhan Hertz Power Equipment Co., Ltd. is an electrical and power equipment manufacturer, seller, repair provider, and technical service supplier based in Wuhan, China. It holds ISO9001:2015 and ISO14001:2015 certificates, reports available SDK capability, design-based customization, four production lines, inventory capability, and documented finished-product inspection instructions. Its stated product output includes cable fault locators, transformer oil hipot testers, relay protection testers, power frequency test devices, and series resonance AC test sets. The supplier exports primarily to North America, with exports representing 51%–70% of total sales and seven years of export experience. However, it reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, no outsourcing SOP, and no continuous quantity reconciliation for each batch. Evidence of customer cases and after-sales execution is insufficient.
Supplier typeThe supplier is identified as a China-based manufacturer and seller of instruments, electrical and power equipment, and mechanical equipment, with repair, research and development, software, and technical service activities. Its registered and physical addresses are the same Wuhan location, supporting classification as an equipment manufacturer and technical-service provider.
CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates. These explicitly demonstrate quality-management and environmental-management certification, although no certificate scope or validity dates are provided.
R&D capabilityThe supplier reports available SDK capability and includes equipment research and development, software development, technology development, consultation, and technical exchange in its scope. These facts support technical-development capability, but no R&D investment, patent, product-development record, or engineering-team scale is provided.
Production capacityThe supplier reports four production lines, inventory capability, and stated annual product outputs across five categories, including 500 cable fault locators, 1,000 transformer oil hipot testers, 1,000 relay protection testers, 800 power frequency test devices, and 500 series resonance AC test sets. Capacity controls have weaknesses: there is no valid manufacturing-capacity contract with related subcontractors, no continuous batch quantity reconciliation, and no outsourcing SOP.
Customization capabilityThe supplier explicitly reports customization from customer designs. This is direct evidence of design-based customization capability, although the available information does not specify engineering scope, tooling capability, lead times, or customization limitations.
